“…Yeah, I knew someone who had extreme breast pain premenstrually, and she found that a quick application of ultrasound relieved it completely. And it's been known for quite a while that any injured tissue repairs itself faster under the influence of mild ultrasound. Bone injury heals faster, and I'm sure that would apply to tendon and ligament injury too. But you want to keep it away from your head. I don't think it's good to risk brain emulsification by too much ultrasound.”
